Application filed June 29, 1916. Serial No. 106,629.

To all whom it may concern:

Be it known that I, Jnss G. BosToN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Combined Knives andSharpening-Stones, of which the following is a specification.

This invention relates to pocket and similar knives and has as itsobject to provide, in conjunction with the handle of such a knife, meansfor housing in the said handle a hone or other type of abrading orsharpening element in such manner that the neat appearance of the knifewill be retained and its ordinary use in no way interfered with, and yetto permit of the ready removal of the hone or the like for use insharpening the knife blades, and its ready replacement.

Another aim of the invention is to provide novel means for removablysecuring the housing for the hone in place on the handle of the knife,so that while the hone will not be liable to loss, it may be readily.removed and replaced in the accompanying drawings:

Figure l is a plan view of a pocket knife equipped with the presentinvention;

Fig. 2 is a vertical longitudinal sectional view therethrough, partly inelevation;

Fig. 3 is a sectional view substantially on the line 3 3 of Fig. 2;

Fig. 4 is a transverse sectional view on the line 4:% of Fig. 3, and

Fig. 5 is a sectional detail.

In the drawings, the numeral 5 indicates a pocket knifeof the generaltype and the numeral 6 the plates of the handle between which the bladesof the knife lie when closed. At one side the knife handle is pro videdwith the usual butts and scale but at the other side the scale of thehandle is omitted, the handle butts at this side being indicated one bythe numeral 7 and the other by the numeral 8. The numeral 9 indicates ahone or other type of sharpening element which is disposed, when not inuse, against the outer face of the plate 6 and which is housed in amanner to be now explained.

The housing for the hone 9 comprises a shell which is preferably formedof sheet metal and which consists of a back 10 provided with marginalflanges 11, this housing being positioned against the plate 6, with theedges of the flanges abutting against the face of the plate and lyingflush with the longitudinal edges thereof. The butt 7 is formed with anundercut recess 12 in its inner end, and the corresponding end of thehousing shell is provided with a marginal flange 1.3 having a struck-outextension lt adapted to fit within said recess, whereby this end of thehousing shell is held against upward as well as lateral separation fromthe butt 7. The hone 9 is pivotally connected to the housing shell, oneend of the hone bein fixed within a sleeve 9" fitting between thefianges 11 and pivoted thereto as indicated at 9. The rear end of theshell has an indentation 15 forming a keeper aperture for a latch. Thebutt 8 adjacent to the keeper aperture 15 has a recess 16 pr0- videdwith a throat 17 in which is slidably mounted a latch 18 having a tongue19 pcsitioned to enter the keeper aperture 15. In order that this latchmay be manipulated, the butt 8 is formed with a slot 20, and the latchis formed with a finger piece 21 which projects outwardly therefrom andthrough said slot, in position to be engaged by the finger for thepurpose stated. Secured at one end, as at 22, within the recess 16 inthe butt 8, is a leaf spring 23 which bears against the end of the latch18 and tends to project the tongue thereof into engagement with thekeeper aperture.

From the foregoing description of the invention it will be understoodthat when it is desired to use the hone, the latch which holds thehousing shell in place may be retracted and the said shell removed so asto permit of removal and use of the hone. The hone is preferably to belaid upon a flat surface during the time of its use and may be held bythe fingers, or, if desired, the last described end of the housing shellmay be disposed to overlie one end of the hone for the purpose ofsteadying the latter while it is being used The pivotal support of thehone 9 enables the same to be swung up as shown in Fig. 5, and outwarduntil it eX- tends in longitudinal alinement with the shell 10. Now, theshell need only be held in the hand during the sharpening process, andthe hone will lie steady, there will be no danger of cutting the fingerswith the knife blade.

I claim:

The combination of a. member havin spaced butts on one side, a housingmounted and, furthermore,

on said member between the butts" and composed of a shell having a backand marginal side flanges inwardly directed and engaging the face of themember, one of the butts having an undercut recess in its inner end, andthe corresponding end of the shell having a marginal flange providedWith an extension fitting in such recess, a latch for locking theopposite end of the housing to the adjacent butt, and asharpeningelement mounted in 1 the housing and pivotally connected to the sideflanges thereof.

In testimony whereof I afiix my signature.

JESS G. BOSTON.
